George, Duke of Bavaria-Landshut, nicknamed 'the Rich', and his wife
Hedwig (Jadwiga) of Poland had no surviving son, so George named his daughter
Elisabeth as his heir in his testament of 19 September 1496, along with her fiancé
Ruprecht of the Palatinate and any future sons the couple would produce. Their marriage was concluded on 10 February 1499. Elisabeth was Ruprecht's cousin, Ruprecht's mother
Margarete of Bavaria-Landshut was George's sister. Nonetheless, this arrangement stood in contradiction to the
Treaty of Pavia (1329), the dynastic law of succession of the
House of Wittelsbach. It stated that if one branch should become extinct in the male line, the other would inherit. Also, according imperial law a Duchy would fall to the
Emperor, should a line fail to produce male heirs; the Emperor would then assign the duchy to a succcessor. Duke
Albert IV of Bavaria-Munich did not accept George's decision to disinherit him. After George's death on 1st of December 1503, this unresolved dispute escalated into the War of the Succession of Landshut, especially after George had named Elisabeth's husband Ruprecht his co-regent shortly before his death. On 13 December 1503, a
Landtag took place in
Landshut which had been called by George. There, Albrecht reaffirmed his claims through envoys, while Ruprecht, who had already taken up residence in Landshut attended in person. It became evident that many of the attendants that had already opposed Albrecht in the
Löwlerbund still harboured reservations against him. The Lower Bavarian
Landstände formed a regency council and appealed to the
Reichskammergericht. King
Maximilian I summoned the parties to
Augsburg for a meeting on 5 February 1504. There and in following sessions, he claimed territories from both sides as compensation for mediating the conflict. In April 1504, Albrecht declared his will to part with the territorries of
Kufstein,
Kitzbühel and
Rattenberg, in turn receiving Maximilian's support consisting of 10,000 troops and monetary assistance. On 23 April, Maximilian formally granted Lower Bavaria to the dukes of Munich. In the meantime, Elisabeth and Ruprecht had dissolved the regency council in Landshut on 17 April. Ruprecht's Palatine troops occupied Landshut, the residential city of
Burghausen and various other towns. After Ruprecht's father, the Elector Palatine
Philipp the Upright, had declared support for his son, war was waged on
Palatine territorries as well. He was supported even by the Kings of
France and
Bohemia as well as the
Margrave of Baden, bringing his troop count up to around 30,000. Albrecht, on the other hand, had 60,000 troops at his disposal. Next to Maximilian's force he was supported by the
Swabian League, Duke
Ulrich of Wurttemberg, Margrave
Frederick I of Brandenburg-Ansbach and the
Free Imperial City of Nuremberg, who sent 5,000 men. King Maximilian declared an
Imperial Ban on Ruprecht and his father Philipp on 5 May 1504. The War of the Succession of Landshut marked the end of a decades-long conflict inside the Wittelsbach dynasty. Main protagonists were the lines of Bavaria-Landshut and Bavaria-Munich, as well as King Maximilian I of the
Habsburg dynasty. In the beginning, it was Albrecht IV of Munich who led a more offensive course in opposition to the imperial Habsburg family, but the dukes of Landshut were no less hostile to the Habsburgs. The traditionally close bond between dukes George and Albrecht rapidly deteriorated after 1493. Albrecht's succession seemed safe with the birth of his son
William. George on the other hand tried to secure his own succession through a political change of course: he allied with the Electoral Palatinate, which was not acceptable for Albrecht. King Maximilian supported the latter, who was married to his sister
Kunigunde of Austria, not the least due to his own ambitions that always had the dynastic claim to hegemony of the Habsburg dynasty at heart. == Development of the War ==
